php: require_once

[joemorris86]

Is there a way to change

<?php
require_once($_SERVER['DOCUMENT_ROOT'].'/myfile.php');
?>

So if 'myfile.php' cannot be found it loads a error message instead of showing the fatal errors?

Try this...

<?
if(!@include_once($_SERVER['DOCUMENT_ROOT'].'/myfile.php'))
echo "Error, this file could not be included";
?>

Cool that works Is there anyway to make it terminate the code aswell as displaying the message? Using the die command somehow ?

Change the echo line to:

die("Error, this file could not be included");

Suppressing errors is lazy coding. Use functions intended for this purpose, such as is_readable() or file_exists().

The man has a point .

Yup. And then handle errors properly via a routine, rather than just with die()

 

[joemorris86]

How would I add a routine to this? Is it hard? Also, do you guys reccomend is_readable or file_exists?

<?php
$filename = 'test.txt';
if (is_readable($filename)) {
echo 'The file is readable';
} else {
echo 'The file is not readable';
}
?>

To throw another spanner in the works, remember that in some instances (I've only encountered it with safe_mode on) a file may not actually be readable despite is_readable() returning true.

 

[Beansprout]

You can use safe-mode-aware file_exists() to check it exists (as it returns false if a file can't be accessed due to safe mode restrictions) and then if it returns true use is_readable() to check you can read it.

I think that would work, anyway
